Two cylinders $A$ and $B$ of equal capacity are connected to each other via a stop cock. A contains an Ideal gas at standard temperature and pressure. $B$ is completely evacuated. The entire system is thermally insulated. The stop cock is suddenly opened. The process is :

An ideal gas goes through a reversible cycle $a\to b\to c\to d$ has the $V - T$ diagram shown below. Process $d\to a$ and $b\to c$ are adiabatic....  The corresponding $P - V$ diagram for the process is (all figures are schematic and not drawn to scale)

What is an isothermal process, adiabatic process and isobaric process ? Write the first law of thermodynamics for an ideal gas.

A cycle tyre bursts suddenly. This represents an

The pressure and density of a diatomic gas $\gamma  = 7/5$ change adiabatically from $(P, d)$ to $(P', d').$ If $\frac{{d'}}{d} = 32,$ then $\frac{{P'}}{P}$should be

An ideal gas at ${27^o}C$ is compressed adiabatically to $\frac{8}{{27}}$ of its original volume. If $\gamma = \frac{5}{3}$, then the rise in temperature is........ $K$
